This is definitely not my understanding, some of the PCI IDs in our
driver are clearly marked as GT1 on the spec.
But since we don't use this GTX number anywhere for CNL for the Kernel
driver, can't we just KISS and go with intel_cannonlake_info until we
actually need it?
Besides that, I really think this patch should be split in 2: one that
only adds the new PCI IDs, and another that does the macro/info rework.
This should help any possible backports.
